Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a movable roof that can be freely erected and relocated, for example, at an event site.

“Conventional technology” For example, as an event venue, there are various exhibition venues, exhibition venues, and presentation venues equipped with stages, etc., but these event venues have traditionally been installed indoors, and vice versa. Installed outdoors, or with an eaves-shaped roof only on the stage at the presentation site, etc., with only the roof fixedly supported by pillars (for example, Expo Festival Plaza) There was such a thing.

"Problems to be solved by the invention" By the way, it is not possible to see the event outdoors or to enjoy sports while being exposed to the warm sunshine outdoors, even in the mild weather such as spring and autumn. It is very pleasant and doubles the fun. On the other hand, everyone will have the experience of being disappointed because the event they were looking forward to was canceled due to rainy weather, or tired of attending the event in hot summer in midsummer. On the other hand, a covered space with a roof has the advantage that you do not have to worry about the weather, especially rain, but it has the drawback of lacking a feeling of openness. The covered space and the covered space have opposite advantages and disadvantages.

The present invention has been made in view of the above circumstances, and creates two situations of the above-mentioned contradictory nature, that is, the outdoor situation and the covered situation, in the same space, and by utilizing them arbitrarily, only the advantages of both are utilized. Its purpose is to provide a roof that can be used.

"Means for Solving Problems" Therefore, in order to achieve the above-mentioned object, the present invention provides a roof,
By forming a plurality of divided roof bodies having substantially the same cross-section between a pair of girder beams forming a structure composed of columns and beams and slidingly moving these divided roof bodies along the girder beams, A movable roof that allows the roof to be erected on and removed from the structure, and a slide mechanism is provided between the split roof body and the girder beam, and at least one of both ends of the girder row direction above the structure. Provides a roof storage unit provided with an elevating device for storing the divided roof bodies in a stacked state.

"Operation" The roof can be erected on the structure and the roof can be removed from the structure arbitrarily, and it is possible to freely cope with the weather and the like. Moreover, it does not require a large space to move out the roof.

[Example] An example of the present invention will be described below with reference to the drawings.
1 to 5 show the present invention applied to a baseball field which is one of the event facilities.

In the figure, the reference numeral 1 indicates a baseball field, which is approximately circular with a diameter of about 200 m. Then, the structure 2 is formed in such a manner as to surround the baseball field 1 and the upper part thereof.
The structure 2 is composed of columns 3 and beams 4, and in this embodiment, the girder size is larger than the diameter of the baseball field 1 and the inter-beam size is slightly smaller than that. Note that structural details are omitted in these drawings for simplification.

On the upper part of the structure 2, four split roof bodies 5 are provided extending between a pair of girders 4a constituting the structure 2.
The split roof body 5 is a truss structure body made of drass with a roof plate on the upper part thereof.
Form the roof of the structure 2 by being integrated with each other in an adjacent state. The size of one of the split roof bodies 5 in the direction of the girder row is approximately one sixth of the girder row of the structure 2.

A track 7 extending over the entire length of the girder beam 4a is formed on the girder beam 4a, and support legs 6 at both ends of the split roof body 5 for supporting the split roof body 5 correspond to the track 7. ing.
The track 7 is of a groove type as shown in FIG. 4, and the bottom surface of this groove is a synthetic high-strength material such as tetrafluoroethylene (commonly called Teflon) having wear resistance and lubricity over the entire length of the track 7. The molecular material 9 is laid and hard rubber 10 is provided on the side surface of the groove.
Is attached. On the other hand, the bottom surface of the supporting leg 6 corresponding to this groove is machined sufficiently smoothly, and the sliding roof 5 is configured so that the split roof body 5 can move on the track 7 by a slide mechanism composed of the track 7 and the supporting leg 6. It is possible to slide along the girder 4a in two opposite directions. The movement of the split roof body 5 is performed by a driving device (not shown).
In addition, roof storage portions 11 extending over the entire beam length of the structure 2 are provided at both ends in the girder direction above the structure 2, and the split roof body 5 that slides can be stored here. it can. The track 7 extends to the inside of the roof storage section 11.

The dimension of the roof storage portion 11 in the girder direction is slightly larger than that of the split roof body 5, and the height thereof is higher than that of the roof formed by the split structure roof body 5 on the track 7. Has become. The roof storage units 11 each include a lifting device 12 inside. The lifting device 12 is at the top,
That is, the drive mechanism 12 provided at the top of the roof storage unit 11
a and a holding mechanism (not shown) that extends to the lower part of the storage part, and is operated by the operation of the elevating device 12 so that it is placed directly under the elevating device 12, that is, on the track 7 and inside the roof storage part 11. The roof body 5 can be lifted and held inside the roof storage portion 11, or conversely, the divided roof body 5 can be placed on the track 7 from that state.

Next, the operation of the movable roof configured as described above will be described.

The four divided roof bodies 5 are adjacent to each other and the structure 2 is provided.
When installed in the center of the upper part, these split roof bodies 5
Becomes an integral roof and covers the upper part of the ground of baseball field 1. As described above, since the size of one split roof body 5 in the girder direction is approximately one sixth of the girder row of the structure 2, in the above state, the split roof body 5 is provided at both ends of the structure 2. Although the roof is not formed, a roof storage portion 11 is formed at each position, and these roof storage portions 11 serve as the roof of that portion.

The baseball field 1 has a roof on the upper side so that a game can be played even in the rain, and in the hot summer in midsummer, it is possible to block the strong sunlight.

On the other hand, in order to move out the roof of the structure 2, first, the drive device is operated to move the outer two of the four divided roof bodies 5.
Each piece is pulled toward the roof storage section 11. That is,
The two divided roof bodies 5 will move in the directions in which they separate from each other. The split roof body 5 can be easily moved by the support legs 6 of the split roof body 5 sliding within the track 7 on the synthetic polymer material 9 provided therein.
The split roof body 5 slides and moves to the roof storage unit.
If it is located inside 11, the divided roof body 5 is lifted up by the height (thickness) of the divided roof body 5 by the drive mechanism 12a of the elevating device 12 provided inside the roof storage portion 11, and further illustrated. The suspended split roof body 5 is held at that position by a holding mechanism that does not. As a result, the two split roof bodies 5 are stored in the roof storage portion 11, and a space for one split roof body 5 is formed in the lower portion of the roof storage portion 11. Then, the two split roof bodies 5 remaining in the erected state in the upper center part of the structure body 2 are pulled by a drive device in the same direction as described above, respectively, in the roof storage unit 11, that is, the above-mentioned split roof bodies are upward. It is placed in the space created by being lifted up. That is, these split roof bodies 5 are stored in the roof storage portion 11 in a state of overlapping the lower portion of the split roof body 5 previously stored in the roof storage portion 11 (see FIG. 5). As a result, all the roofs of the structure 2 have been moved out (excluding the fixed roof portion formed by the roof storage portion 11). That is, the roof covering the upper part of the baseball field 1 can be retreated, and the blue sky and warm sunlight can be enjoyed.
In this way, since the relocated roof bodies are stored in the roof storage unit 11 in a stacked state, it is possible to minimize the sacrificed (wasted) space even in the relocated state,
The function can be exhibited while effectively utilizing the limited space.

From this state, in order to obtain the state in which the roof is formed as described above, the above-described retreating method may be performed in reverse. At this time, with respect to the split roof body 5 stored above the roof storage portion 11, that is, with respect to the split roof body 5 previously stored, the step of lowering the one above and placing it on the track 7 is performed. However, since the track 7 of the slide mechanism is of the groove type as described above, the support leg 6 of the split roof body 5 to be engaged with this is automatically positioned while being guided in this groove. .

In addition, in the present embodiment, the structure 2 for erection of the divided roof body 5
Although the beam span (span) is slightly shorter than the baseball field 1, it is of course possible to make the span longer so as to cover the entire baseball field 1. Further, in the case where a long span is taken as described above, the prestressing of the truss beam forming the divided roof body 5 by the PC steel material is applied to the lower chord member to reduce the deflection of the beam due to the load. The weight of the beam has been reduced by (Japanese Patent Application No. 60-175997 "Truss Beam",
It can be effectively realized by making the application already filed by the applicant etc.). Further, in the present embodiment, the entire roof of the structure 2 is formed by four divided roof bodies 5, but the width (column row) of one of the divided roof bodies 5 is made small and at the same time the number of divisions is increased. It is also possible to increase the number, and in that case, the width of the roof storage portion 11 can be narrowed accordingly. Further, in the slide mechanism, in addition to the above-mentioned means, for example, a large number of steel balls are randomly placed in the groove of the track 7 and the rolling of the steel balls is utilized to enable the movement of the support leg 6. It may be one. Further, the means for sliding movement of the split roof body 5 is not limited to the one that is pulled by the drive device provided outside the split roof body 5 as described above, and for example, the slide mechanism is configured by rails and wheels. Then, a drive device may be incorporated in the support leg 6 so that the split roof body 5 can be self-propelled on a rail like a gate type crane. In this case, the wheels are wider than the rails, and the cross-sectional shape of the contact portion with the rails is a large U-shape, so that the support legs are mounted on the track from the roof storage section. Don't let things that don't go well in.

[Advantages of the Invention] As described above, the present invention forms the roof into a plurality of divided roof bodies having a cross-sectional shape that is substantially the same between a pair of girders that form a structure including columns and beams. A movable roof that allows the roof to be erected on and removed from the structure by slidingly moving the split roof body along the girder beam, and a sliding mechanism is provided between the split roof body and the girder beam. And, since at least one of both ends in the girder direction in the upper part of the structure is provided with a roof storage unit including an elevating device for storing the divided roof bodies in a stacked state,
The roof with a stepless roof surface to the structure can be erected, and the roof can be withdrawn from the structure arbitrarily, and it is possible to cope with the weather freely and moreover, because the split body slides Only one track, such as a rail, should be provided for each girder in the girder, and the roofs that have moved out will be stored in the roof storage section in a stacked state. Space can be minimized,
Various excellent effects are exhibited such that the function can be exerted while effectively utilizing the limited space.
